Col - the injected Pinto was used in the very last of the Pinto Sierras. Mine is from an E-reg (1988ish). I dont think there are many about. Ive been
told its worth getting the full lump if in reasonable nick as they are supposed to have stronger rods and good for rebuilding into 2.1's (205
block).

Injection engine is better for tuning apparently yes. There's quite a bit about it in the Des Hamill book. The injection head has a better inlet
port shape (the ports is also bigger iirc) so need less machining to get it to the best size/shape.
AFAIK all the injection engines were 205 block. Not sure about the stronger rods though...

Ive just ported my injected head as per hammil book (not quite as far as recommended but close). It was quite easy to do (used small die grinder with
a £50 B&Q compressor - worked very well albeit slow going). Des does say that if you are going to port a head you dont necessarily have to start
with the iS head first as any will end up the same shape after a lot of work. This suggests that for minimal work the standard head can be modded to
flow as per iS head - the book is an essential read.
The Des book (Pg17) says the later cast rod is capable of withstanding 7K rpm on a continual basis (just). 7.5K with forged pistons but not on a
continuous basis if engine is rebuilt regularly and rods changed. Earlier rods OK to 6.7K continuous.
Please dont take my word for it though, im no expert just have the book.
